Mucin 1 knockdown in EMM myeloma cells

The sialic glycoprotein, Mucin1, is known to be involved in the pathogenesis of various types of cancers. In a fraction of patients with multiple myeloma, their myeloma cells have high Mucin1 expression. We established a myeloma cell line designated EMM1 from a myeloma patient whose myeloma cells have high Mucin1 expression. Then we performed knockdown of Mucin1 to elucidate the role of the high Mucin1 expression. Overall design: we performed knockdown of Mucin1 to elucidate the role of the high Mucin1 expression. Knockdown of MUC1 in EMM1 cells induced cell cycle arrest during S phase and apoptosis in EMM1 cells. To elucidate the role of Mucin1 in EMM1 cells, we generated EMM1 cells lines expressing shMucin1 or control shRNA and performed RNA-seq analysis of the two cell lines and compared the differences in gene expressions.
